Generate a table for a byte-wise 32-bit CRC calculation on the polynomial:
x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
Polynomials over GF(2) are represented in binary, one bit per coefficient,
with the lowest powers in the most significant bit. Then adding polynomials
is just exclusive-or, and multiplying a polynomial by x is a right shift by
one. If we call the above polynomial p, and represent a byte as the
polynomial q, also with the lowest power in the most significant bit (so the
byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
where a mod b means the remainder after dividing a by b.
This calculation is done using the shift-register method of multiplying and
taking the remainder. The register is initialized to zero, and for each
incoming bit, x^32 is added mod p to the register if the bit is a one (where
x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
x (which is shifting right by one and adding x^32 mod p if the bit shifted
out is a one). We start with the highest power (least significant bit) of
q and repeat for all eight bits of q.
The table is simply the CRC of all possible eight bit values. This is all
the information needed to generate CRC's on data a byte at a time for all
combinations of CRC register values and incoming bytes.

* Image Types
*
* "Standalone Programs" are directly runnable in the environment
* provided by U-Boot; it is expected that (if they behave
* well) you can continue to work in U-Boot after return from
* the Standalone Program.
* "OS Kernel Images" are usually images of some Embedded OS which
* will take over control completely. Usually these programs
* will install their own set of exception handlers, device
* drivers, set up the MMU, etc. - this means, that you cannot
* expect to re-enter U-Boot except by resetting the CPU.
* "RAMDisk Images" are more or less just data blocks, and their
* parameters (address, size) are passed to an OS kernel that is
* being started.
* "Multi-File Images" contain several images, typically an OS
* (Linux) kernel image and one or more data images like
* RAMDisks. This construct is useful for instance when you want
* to boot over the network using BOOTP etc., where the boot
* server provides just a single image file, but you want to get
* for instance an OS kernel and a RAMDisk image.
*
* "Multi-File Images" start with a list of image sizes, each
* image size (in bytes) specified by an "uint32_t" in network
* byte order. This list is terminated by an "(uint32_t)0".
* Immediately after the terminating 0 follow the images, one by
* one, all aligned on "uint32_t" boundaries (size rounded up to
* a multiple of 4 bytes - except for the last file).
*
* "Firmware Images" are binary images containing firmware (like
* U-Boot or FPGA images) which usually will be programmed to
* flash memory.
*
* "Script files" are command sequences that will be executed by
* U-Boot's command interpreter; this feature is especially
* useful when you configure U-Boot to use a real shell (hush)
* as command interpreter (=> Shell Scripts).
